Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves for protection.

2. Replace Brake Pads and Rotors (if worn)

Tools Required: Socket set, torque wrench, jack stands, brake cleaner, brake grease
Loosen wheel lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the wheel to gain access to the brake components.
Remove the caliper by unbolting it from its bracket. Support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect rotors for damage; if warped or excessively worn, remove them by unbolting the rotor from the hub.
Install the new rotor, securing it to the hub with the specified torque.
Apply brake grease to the back of the new brake pads and reinstall them in the caliper bracket.
Reattach the caliper and torque bolts to the manufacturer’s specifications.
Repeat the process for the other side if necessary.

3. Address Brake Fluid Issues

If low fluid was detected, check for leaks and repair as needed.
If the master cylinder is faulty, replace it as follows:
- Disconnect battery.
- Remove the master cylinder from the brake booster by unbolting it.
- Install the new master cylinder and torque to specifications.
- Bleed the brake system to remove air from the lines.
